Dry ice blasting uses dry ice as the abrasive medium. Pressurized air propels small dry ice pellets at the coating. The effect of the pellet hitting the surface and the dramatic temperature change as the dry ice cools the surface cause the contaminants to fall away. Because dry ice evaporates at -109°F, the abrasive simply disappears after impact, minimizing cleanup and eliminating potential interference with mechanical parts.
Dry ice blasting is an effective blasting method for cleaning and restoration, and dry ice has been approved by the FDA, EPA, and USDA as an acceptable cleaning material. This means dry ice blasting it is excellent option for food safe cleaning.
